Re: HELP - ON BROWSER, Applets, JMF & Swings & Plugins - Applet deployment
hiiiiii,
plz send me ur working code of media player in java .i need this for my major project.i m facing problem with media package .
thnx.
Oh, I see. IE makes you use the Information Bar:
IE 6 has an "Informat Bar" that appers at the top of the HTML content.
When I copy and compile your example in a temporary directory and enter the URL in IE6:
C:\temp\WelcomeApplet.html
There is a message:
TItle: Information Bar
Did you notice the information Bar?
The Information Bar alert you when Internet Explorer block a
pop-up window or file download that might not be safe. If a
Web page does not display properly, look for the information
Bar (net the top of your browser)
[Checkbox] Do not show this message again.
(link) Learn about the Information Bar
(button) OK
I click OK
and the Information Bar says:
To help protect your security, Internet Explorer has restricted this file from showing active content that could access your computer. Click here for options...
I click on the Information Bar and a context menu appears:
Allow Blocked Content...
What's the Risk?
Information Bar Help
I choose Allow Blocked Content...
Title: Security Warning
Allow active content such as script and ActiveX controls can be useful,
but active content might also harm your computer.
Are you sure you want to let this file run active content?
Yes/No
I choose Yes
It works for me in IE 6

How to find browser have java swing plugins
how to find browser have java swing plugins
Hi, you can detect it. If it is not there, you can make the installation automatically. Here is an example.This will not work with NN4 browser unless the user has Enable Java Plugin checked (see Edit | Preferences | Advanced. Nor will it work under IE if the user has disabled Java.
The best solution, IMHO, is to trigger a JavaScript function and check to see if the applet is created. You can try:
<html>
<head>
<title>....</title>
<script>
function checkApplet() {
if (document.myApplet!!=null) return true;
alert("You need to enable Java and have the proper plugin to view this document:);
return false;
</script>
<noscript>You need to turn on JavaScript to view this page</noscript>
<body onLoad="checkApplet()">
...... // applet tag goes here
</body>
</html>
Remember that you cannot call your applet to test its status.

Swing based applets don't run in browser !!!
whenever i run a swing based applet from the browser (IE 5), the applet is not displayed in it - status bar shows that the class file was not found
so please tell me the solution
thanx in advance!You just have to download Sun JVM to run swing JApplet in your browser(IE).
get it at the following address:
Just follow the link, and download dialog will be appeared just save the file to you hard drive, and install the software.
The file name will be : "j2re-1_4_1_02-windows-i586-i.exe"
http://java.sun.com/webapps/download/AutoDL?BundleId=7544
after successfull installation you'll find the new plugin
"java2 v1.4.1_02 for<applets>"
in Tools>InternetOptions>Advance
you have to check it(if unchecked) to enable the JApplet to be loaded in your browser.
Another new option you'll find in your Tools menu "Sun Java Console". From it you can find what exceptions are thrown while the applet is loaded -
HELP, Diagnostics Applet JMF classes.....Not Found
Hi,
I installed JMF and verified the jars are included in classpath and path, but when I run the diagnostic applet page, it still says Applet JMF classes not found, anyone has any idea?
classpath:

JMF classes.....Not Found
http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/jmfdiagnostics.htmlEverything looks fine as far as the setup goes... Unless you're having problems with a specific JMF application, I wouldn't worry about the diagnostic applet telling you it isn't installed correctly.
Very well could be a browser security issue with the applet... -
Hi
I developed a applet using swing componets.But it doesn't work.
I used jdk1.3.1 for development.And I am using IE 5.0 and Netscape4.7 browsers.
can any body help me what could be the problem?
thanksJust explain the problem, might be i can help u.
Any ways u should have the Plugin to run the Swing applet.
Best of Luck!

Security problem when signed applet dynamically load plugins
Hi!
I have one problem : "security problem when signed applet dynamically load plugins"
This is the scenario:
the main program [app.jar]
. contain applet and shared library (interface & implement of common class)
. it is signed and run normally on browser
. it can draw image loaded from other URL [ex] http://bp1.blogger.com/image.jpg
. the image loader is in the shared library
. dynamically load amazon.jar through URLClassLoader and reflection
the plugin [amazon.jar]
. search amazon product [ex] Harry Potter book
. draw image on applet
. use image loader from shared library, BUT CANNOT LOAD IMAGE
The question: "Why it cannot load image, because the image loader is in the shared library which has been signed and working?" I tried to sign the amazon.jar too, but it did not work.
Your reply would be very helpful. Thank you.
Sovannhello. i have create a signed applet for A.jar. A.jar include two package B and C. the main applet class is within B.
B need some classes in C to run the applet. but i got the error that class in package c are not found.
what shall i do? -

HELP!!!!!! Applet has messed up my JSC
During the test of integrating applet into JSF pages, my JSC IDE suddently got a problem with applet. Please help me out!!!
My applet test project:- Open a new project
- Drop a Label, a Button, and a StaticText into page
- Set button action as "label1.setText("click");"
- Uncheck "escape" property of StaticText and Set "Text" to <applet/>
Compile and Run the project- A square box with "x" is shown (this is right for the applet in the page)
- BUT CLICKING BUTTON GETS NO ACTION!
If I remove <applet/> from StaticText, Everything is fine.
Do the same thing using JSC on another computer:- Everything works fine even though I integrate a real applet class.
Uninstall my JSC2
Delete folder /Program Files/Sun/Creator2, and /doc and settings/user/.Creator,
Clean up Registry and restart computer
Download JSC 2 update 1
Install JSC 2 update 1
Try the applet test project- EVEN WORSE! THE BUTTON DOES NOT SHOW UP!!!
- It only works if I remove the <applet/> from staticText
Can anyone here help me out? Any help is really appreciated!
Thanks in advance,I've tried in both and it looks like the IE submit somehow gets broken when there is a problem with the applet. You get the following exception in the Java Console.
java.lang.NullPointerException
at sun.plugin.util.GrayBoxPainter.showLoadingError(Unknown Source)
at sun.plugin.AppletViewer.showAppletStatus(Unknown Source)
at sun.applet.AppletPanel.createApplet(Unknown Source)
at sun.plugin.AppletViewer.createApplet(Unknown Source)
at sun.applet.AppletPanel.runLoader(Unknown Source)
at sun.applet.AppletPanel.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)I was able to get an applet working with a Creator app in IE when the <applet> tag contained valid applet information. Please try continuing to build the web application with a VALID set of applet tags (that won't break).
Cheers!

IE7 Browser hangs while displaying an applet of larger size
Hi
My IE7 Browser hangs while displaying an applet of larger size with jre version update 12. The java.exe utilization is 99%.
Can somebody please help me out.
Thanks
AnnYou haven't given much details. The problem is probably related to the applet and not the plug-in

Hi all, I've been wondering if applets can be dynamically called from a jsp or servlet using strings in the applet code section. would this be good if a database was used to store the paths of the applets?
i've tried this with a small applet in different ways, just to see the effect in Apache Tomcat 4.1.24, but it didn't really work. could anyone help me out here?
the coding i've been using is below :
<%@ page contentType="text/html; charset=iso-8859-1" language="java" import="java.sql.*" errorPage="" %>
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body>
Here is the applet!
<br>
<jsp:plugin type="applet" code="ElecBill_a" codebase="." height="200" width="200" >
<jsp:fallback>
<p> Unable to use Java Plugin</p>
</jsp:fallback>
</jsp:plugin>
<br>
<applet code = "ElecBill_a.class" height="200" width="200"></applet>
//up to here it works fine, both applets appear. but below, the string is read directly and causes an error
<%! String myapplet = new String("ElecBill_a"); %>
<%! public String getName() {return myapplet; } %>
<br> The name of the class file is <%= getName() %>
<br>
<jsp:plugin type="applet" code="<%= "myapplet" %>" codebase="." height="200" width="200" >
<jsp:fallback>
<p> Unable to use Java Plugin</p>
</jsp:fallback>
</jsp:plugin>
</body>
</html>yes, i suppose it doesn't. i've tried to insert it using the original way with the applet tag like this
<APPLET code = <%= getName() %> width=300 height=300>

Do I need to make an applet with swing point to the JRE 1.4 plug-in?
Do I need to make an applet with swing point to the JRE 1.4 plug-in? I mean, in 1.3.1 plug-in, if you did not run your code through the HTML converter, the applet would still use the browsers JRE (JVM). However, with 1.4.0, it seems that you don't need to. Is this correct?
When you ran an applet that has been compiled under 1.4 and needs classes or methods from 1.4 with an old HTML file (presumedly with the <object> tag that still refers to JRE 1.3+), the browser is going to look at the <object> tag and see that at least JRE1.3.1 is needed to correctly run the applet and since 1.4, which is higher than 1.3+, is on the system, it ignorantly proceeds to load and run the applet. The problem that you're going to run into is when you deploy the applet on the web and your viewer only have JRE1.3+, your applet which really needs 1.4, will crap out....
;o)

I've written an applet using Swing but I'm having huge problems trying to get it to run in Internet Explorer (even though it works in the Applet viewer).
Someone suggested rewriting it using awt so that users with older browsers don't have to download a plugin to be able to view it? Is it necessary to download a plugin to view applets with Swing? Is this better to avoid using packages like Swing if possible, in your opinion? Please let me know what you think - I would like as many people as possible to be able to see the applet on their browsers.
Thanks for your time.It's because of Microsoft and Sun falling out over Java, effectively Microsoft couldn't/wouldn't move beyond 1.1 which was AWT based. At some point in the not too distant future they will remove all Java support so at that point you will be reliant on a plug-in to get to the IE base.
At the moment, if you've already done some AWT work and the GUI is simple, I'd stick with it, otherwise go to Swing and the plug-in. This is of course subjective, others would disagree strongly with me.
